When they begin to consider the issue of insulationsex, then specialists from the very beginning discouraged the introduction of complex systems, since the most common insulating materials are quite able to cope with this task.
Therefore, you should not spend money and energy on the construction of complex structures, but it makes sense to learn how to make a floor screed with expanded clay with your own hands.
With this material it's so easy to work that anyone can handle the screed device, no special equipment or tools are needed.
The only thing that will have to pay attention -this is the thickness of the layer to be laid. It must be at least three centimeters. As a rule, expanded clay is used when it is required to level the floors in all rooms.
Such problems have to be addressed often, andThe material is often used for the warming of floors in private houses, apartments and other premises. Light weight makes the expanded clay even more popular in the construction of insulation screeds, since the whole construction does not weight the slabs having an individual margin of safety. If you want to organize a screed with a thickness of more than 10 cm, then it should be done not just from a pure mixture of sand and cement, but with the addition of a light filler - expanded clay. Often used foam foam or gypsum fiber sheets.
If the floor slabs do not inspire confidence, and you decide to insulate the floor yourself, the floor screed with expanded clay - this is what you need. Is it difficult to do it yourself?
Let's look at how the floor screed works withclaydite with their own hands. The process is not complicated, but will require attention and effort. Expanded clay are ordinary clay balls, subjected to heat treatment. In other words, burnt clay.
First, determine the line along whichit will be necessary to level the floor. It is convenient to use the laser or water level. As a result, horizontal lines should appear on the walls of the room, along which the surface will be leveled.
After the level of the future sex iswalls, you need to get rid of various defects. Do not rely on the fact that the screed itself will fill all the irregularities, notches and chips, since it is necessary to fill the floor with expanded clay, and therefore there is a possibility that it will not be possible to get rid of all the flaws. Therefore, it is better not to spare time and money and to fill them with a liquid solution, similar to that which will be prepared for the screed.
The next important stage of the screed device -installation of leveling beacons. To do this, you have to determine where the highest point of the floor is. Precisely in this place it is necessary to establish the first of the lighthouses. This is the most important moment when you make a floor screed with expanded clay with your own hands.
Lighthouses are ordinary guides made of metal, sometimes made of plastic. They are laid along or across the room, dividing it in this way into sections. Expanded lighthouse between the lighthouse.
To ensure that all guides are in the sameplane, under them lay wooden wedges or just pieces of boards or plywood. However, you can do even easier: dilute the gypsum with water and lay this dough-like mass with a slide along the intended installation site of the guide. The lighthouse should be put on a hill and evenly distributed with a level.
To align long beacons convenientlyuse a rule or a level of two meters in length. When determining the distance between the guides proceed from the size of the rule: the beacons are arranged so that it is convenient to place the tool on two adjacent guides or three. If, for example, the width of the room is four meters, then you should place the beacons at a distance of not more than 70 cm, because then the level will cover not two but three guides, which will positively affect the speed and quality of the work performed.
After the beacons are exposed and aligned,it is necessary to cover the floor with expanded clay. We can assume that the floor screed with their own hands is almost completed. Claydite falls asleep strictly on the marked sites, which limit the lighthouses. Backfilling is considered to be the simplest step in the installation of a screed. The main thing is to monitor the height of the layer of expanded clay. It should be evenly distributed so that there is still room for the screed, that is, for a mixture of cement and sand. In other words, the layer of expanded clay should be such that to the upper level of the beacons there is still 25-20 mm. After the expanded clay is evenly spread between the beacons, we prepare the "milk" from the cement. They fill our heater with water.
This solution is the material called forto fasten the heater. As a result, you can safely walk on the expanded clay layer. In addition, the solution covers the granules with a special film, which reliably protects them from moisture, otherwise the moisture from the liquid cement screed will be absorbed into the expanded clay. This is also necessary because in the event that the screed will lose moisture, the quality of the cement slurry will inevitably decrease. Subsequently, cracks, chips and other defects will appear. In other words, the floor screed with claydite made with this hand will lose its strength.
Следует понимать, что это тот же самый cement-sand mortar, only in liquid form. Here you can not do without experiments. In a mixture of cement and sand, you need to pour three times more water than for a conventional screed. Then fill the resulting solution with a separate small area with expanded clay and see the behavior of the mixture. If it was poured through the expanded clay, and there was not a trace left on the pellets, too much water was added. If there is a residual layer of milk on top of the heater, we can conclude that there is not enough water. It is necessary to find a compromise.
After the entire surface is floodedwith cement milk, it must be allowed to dry completely. It takes at least 24 hours. Only then you can begin the next stage of the work, which will be the actual floor screed with expanded clay with your own hands.
Для приготовления раствора для стяжки используют cement grade not lower than M400 and construction sand, which are mixed in a 1: 3 ratio, respectively. It is better to use a special construction mixer, rather than an ordinary shovel.
Запомните, что обычно добавляют два литра воды на ten kilograms of the mixture. It is much more convenient to pour the solution into the water, and not vice versa, although the instructions attached to the cement often indicate the "wrong" way.
Using a mixer, the mixture is thoroughly mixed infor 5-10 minutes. Then leave for 5 minutes to settle, and after five minutes again stir for about 2-3 minutes. Now you can use the solution.
Filling the solution on the floor, it is leveled with a trowel,applying the rule, if necessary, to distribute the composition evenly throughout the floor. The rule is put on beacons and stretch the cement mass throughout the site, trying to make the surface take a strictly horizontal position, and there were no hillocks and troughs. This is how the floor screed with expanded clay is handled.
There is an easier way to lay clayditea heater under a coupler. Preparation of the base is done exactly as described above. Only the solution is prepared differently. The water is poured into the container and the expanded clay is covered. After this, a cement-sand mixture is poured in, which is mixed thoroughly and quickly and placed between beacons.
In this way, a floor screed is done even more quickly: claydite is a material that will help speed up the process. However, choosing this option is extremely difficult.guess the proportions of its components. In this case, it is recommended to use ready-made mixtures that are sold in hardware stores and markets. They are poured into a container where water is already poured and expanded clay is added. In another way, this method is also called "wet."
There is a “dry” option, and this is also a floor screed withexpanded clay. Features of the technology are that water is added much less. If such a solution is taken in the palm and squeezed into a fist, then no liquid should drip from it. But the disintegration of the mixture is also unacceptable. After such a solution is distributed between the beacons, it must be tamped. It dries quickly enough, and this allows you to start the following stages of construction work without spending time on drying.
This is a standard floor screed withexpanded clay do it yourself. The instructions may vary depending on the specific conditions, but the principle of its creation is the same for most rooms in which the need for leveling floors arises.
Savings - the trump card in ourdifficult time. You should not be afraid that you will not succeed in a floor screed with expanded clay: making a screed with your own hands is an easy process, the most important thing is to comply with the technology and not forget about some important points. Then it will serve you faithfully for a long time, and you will not have to constantly repair the floors.
